Makino EDNC 10 – Sinker EDM
The EDNC10 is the third machine in the EDNC-Series line-up. It provides additional X/Y/Z stroke capacity and is available in a standard and wide-tank configuration. The standard EDNC10 accepts part sizes up to 59.1” x 43.3” (1,500mm x 1,100mm), and the wide-tank version accommodates larger parts up to 78.7” x 43.3” (2,000mm x 1,100mm). Both machine configurations utilize a three-sided programmable rise-and-fall work tank and stationary worktable design that provide unimpeded access to the work tank. The machine design minimizes shop floor space by integrating the dielectric reservoir into the base casting of the machine, improving the thermal stability. The robust and precise machine structure achieves high-level accuracy on workpieces weighing up to 6,600 lbs. (3,000kg).
The EDNC10 can be equipped with optional content that further enhances performance and capability. The HS-Rib high-speed Z-axis option enables jump motions up to 20m/min with 1.5G acceleration and utilizes core cooling of the ballscrew. The system can achieve and maintain precise depth control and is capable of reducing machining times by up to 60 percent, matching the same level of performance and productivity as much smaller machines. Optional ATC (automatic tool changer) systems are also available that allow full utilization of the entire machine stroke without any limitations to achieve higher levels of unattended operation.
The EDNC10 is loaded with advanced technologies that provide the highest level of performance and productivity. The Hyper-i control system fuses the power and flexibility within the machine into a modern and extremely user-friendly interface. Operators of all skill levels will appreciate the streamlined graphical flow and intuitive nature of the large hi-definition touch screen and will be able to make efficient use of the HyperCut and SuperSpark™ IV technologies for optimal results. The Hyper-i control system empowers the operator with additional support and advanced features such as the on-board digital manuals and E-Tech Doctor functions, bringing new levels of capability and operational ease to the shop floor.
• HyperCut: This special generator setting provides improvement to machining speeds without increasing electrode wear or required electrode reduction amount. HyperCut can be used on part details up to 30 amps, and improves machining speeds by up to 30 percent without affecting surface quality.
• SuperSpark™ IV: This family of technologies utilizes dynamic power supply adjustments and jump motion control during the machining process. It enhances automation and unattended operation capabilities by eliminating the need for external flush lines and increases the control’s ability to maintain higher cutting speeds regardless of the application or operator’s experience level. Reduction in rough machining cycle times can be achieved when using SuperSpark™ technology regardless of the shape, size or depth of cavity.
• ArcFree: This set of safety-focused settings virtually eliminates the possibility of the machine developing destructive DC arcs during the course of a burn. ArcFree technology, coupled with Makino’s extremely fast servo control response time, enables safe, unattended burning, even when the current applied to an electrode exceeds its maximum current density. While arc prevention has been a part of all modern sinker EDMs, ArcFree technology is the next advancement in intelligent adaptive controls for prevention of DC arcs.
• Flower pattern: Special conditions were developed to obtain a uniform Ra value surface finish with a large RSm value to improve the performance of mold release for plastic injection tools. The more open structure of the surface finish improves plastic part mold release and tool life while reducing the interval for mold cleaning maintenance.
• HQSF™ (High-Quality Surface Finish): This optional configuration dramatically improves the produced surface finish of tool steels using copper or graphite electrodes. The technology was specifically designed to eliminate post-machine polishing and produce superior metallurgical results that extend tool life. Makino’s HQSF process uses a special µSC powder additive that is mixed in the dielectric oil that enhances the stability and even disbursement of the machining spark energy. HQSF can also provide cycle time reductions when not machining to ultra-fine surface finishes.
• EDcam™ software: Makino has developed an off-line programming system for Ram EDM that makes use of the electrode and work piece CAD model information. The system eliminates the requirement of having to create paper process sheets for manual data entry of the programs on the machine control, which invite critical human errors. By intelligently utilizing available electronic data, the EDcam software brings the Ram EDM process into the 21st century and provides a means of program simulation and verification without the need for time-consuming, on-machine, dry-run operations.
• Remote machine monitoring: As part of efficient unattended machine operation, operators and supervisors alike may wish to monitor the machining progress while away from the machine. Makino offers two software options that provide a means of process updates. The EDM mail option enables the machine to generate e-mail text-based messages on any alarm/stop status or by timed intervals. The EDM viewer option provides direct viewing of the machine control interface on a remote PC.
